Overview
IEC 61310-2:2007, titled Safety of machinery - Indication, marking and actuation - Part 2: Requirements for marking, is a critical international standard developed by the International Electrotechnical Commission (IEC). This standard establishes general rules for the marking of machinery to ensure clear identification and promote safe use by effectively communicating mechanical and electrical hazards. It also addresses the prevention of hazards arising from incorrect connections.
The 2007 edition represents a second edition that revises and updates the original 1995 publication, incorporating important technical changes, including the addition and updating of safety signs in Annex A. It is designed to align with current industrial safety practices, providing manufacturers, safety professionals, and regulatory bodies with a robust framework for marking machinery for identification and hazard avoidance.
Key Topics
-
Marking for Identification and Safety
The standard provides rules on how to mark machinery for identification purposes, safety indications, and warnings related to mechanical and electrical hazards. Effective marking enhances user awareness of potential dangers throughout equipment operation.
-
Marking of Complete Machinery and Components
IEC 61310-2 defines requirements for marking entire machines as well as their components to ensure consistent and clear communication of safety information.
-
Marking of Connections
Special attention is given to the correct marking of mechanical, fluid system, and electrical connections to prevent hazards caused by improper assembly or operation.
-
Durability and Fixation of Markings
The standard requires that markings remain durable and securely attached under normal conditions of use, maintaining visibility and legibility throughout the machinery's operational lifecycle.
-
Graphical Symbols and Safety Signs
Annex A contains updated graphical symbols and safety signs to reflect the latest standards in safety communication, ensuring universal understanding across different languages and regions.
Applications
-
Machinery Manufacturing and Assembly
Manufacturers use IEC 61310-2 requirements to design and apply consistent and effective markings on machinery to comply with safety regulations and standards.
-
Safety Compliance and Risk Management
Safety engineers and compliance professionals implement this standard to reduce workplace hazards, ensure proper machinery use, and facilitate audit processes.
-
Maintenance and Inspection
Clear marking according to IEC 61310-2 aids in safe inspection, maintenance, and troubleshooting by identifying hazardous areas and correct connections.
-
Training and User Instruction
Markings compliant with IEC 61310-2 support operational training programs by visually highlighting mechanical and electrical risks.
Related Standards
IEC 61310-2 is part of the IEC 61310 series, which collectively addresses Safety of machinery – Indication, marking and actuation.
